二分量子系统的维数界

Bounding the dimension of bipartite quantum systems

T. Vértesi, K. F. Pál

摘要:

让我们考虑一个二分量子系统上由两个结果的局域测量所产生的联合量子关联集合。我们证明,没有有限的尺寸是足以产生所有这些集。我们在两种不同的方式来处理这个问题,通过构建每个维度d的明确的例子,这表明存在必要的d维局域量子系统,以产生它们的二分相关。我们还表明,至少有10个两个结果的测量必须由双方一起进行,以产生二分联合相关性无法实现的二维本地系统。我们发现的最小的显式示例涉及11个设置。

英文摘要:

Let us consider the set of joint quantum correlations arising from two-outcome local measurements on a bipartite quantum system. We prove that no finite dimension is sufficient to generate all these sets. We approach the problem in two different ways by constructing explicit examples for every dimension d, which demonstrates that there exist bipartite correlations that necessitate d-dimensional local quantum systems in order to generate them. We also show that at least 10 two-outcome measurements must be carried out by the two parties altogether so as to generate bipartite joint correlations not achievable by two-dimensional local systems. The smallest explicit example we found involves 11 settings.
